//        image shown on the clients website. It should be called
//        on the clients HTML page as a javascript include such as:

//        This js file will show the image of online.gif if an operator
//        is online otherwise it will show offline.gif . Also a 
//        second image is placed on the site as a control image 
//        where the width of the image controls the actions made by 
//        the operator to the poor little visitor..
